BACKGROUND

1. Field

The present disclosure relates to jewelry findings, and more particular, a jewelry setting which provides maximum exposure of a gemstone, while providing a sturdy and attractive mounting for the gemstone. The jewelry setting may be incorporated in a ring, an earring, a pendant, or as a component of a bracelet and the like.

2. Description of the Related Art

Jewelry findings are well known in the art and have been the subject of many issued patents. For example, U.S. Pat. No. 2,835,117 which issued to Lutrario on May 20, 1958 is entitled “GEM SETTING WITH GEM BIASED ORNAMENTAL SADDLE MEMBER”, and discloses a significant and massive gold setting construction, thereby shielding a large portion of the gemstone. Similarly, the patent to Engel, U.S. Pat. No. 2,510,774 which issued on Jun. 6, 1950 provides a stone mounting for bracelets and other articles wherein a major portion of the sides of the gemstone are hidden. Other similar findings or settings which obstruct a portion of the gemstone are disclosed in U.S. Pat. No. 5,433,090 to Santiago which issued on Jul. 18, 1995 and is entitled “VARIABLE FINGER RING WITH BIASED SHANK AND METHOD OF MAKING SAME” and U.S. Pat. No. 5,800,574 to Ricci et al. which issued on Sep. 1, 1998 and is entitled “V-END SETTINGS AND METHOD OF MAKING SAME”.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Preferred embodiments of the present disclosure will be described hereinbelow with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the present disclosure in unnecessary detail.

Turning to FIG. 1, the subject setting or finding 1 comprises a cylindrical frame 12 for receiving a gemstone and a plurality of prongs 14 which include bent portions 15 for gripping of the stone 10. The cylindrical frame 12 includes an annular sidewall 16 and an open bottom or base, designated by the numeral 18, defining a cavity for receiving the gemstone. The aperture defining by the base 18 can be of any size and may vary in accordance with the stone selected for a particular setting. An upper peripheral edge 20 of the cylindrical frame substantially corresponds to an outer diameter of the round stone 10. The prongs 14 are soldered to the sidewall 16 of the cylindrical frame 12, as shown in FIGS. 2 and 3, with the prongs 14 being equally spaced about the perimeter of the cylindrical frame 12.

As shown in FIGS. 2 and 3, the stone 10 rests on the upper peripheral edge 20 of the cylindrical frame 12 of the setting, with the bent portions 15 of the prongs 14 engaging and tightly holding the stone 10 to the finding.

As illustrated in FIGS. 2 and 3, the peripheral portion 11 of the stone 10, e.g. a girdle, is fully exposed, as is the top portion of the stone 10, other than for the small protrusions of the bent portions 15 of the prongs 14. Accordingly, maximum exposure of the stone 10 is effected, thereby resulting in an aesthetically pleasing assembly of the stone and the subject finding.

The frame 12 may be formed from any precious or non-precious metal by any known metal forming process, e.g., a stamping process, to correspond to the shape of the gemstone to be set, e.g., round, oval, square, triangle, emerald, pear, marquise, heart, etc.

Each prong 14 has a generally square cross-sectional configuration, of approximate one half millimeter on each side, and is preferably made of the same metal or material as is the cylindrical frame 12, e.g. gold, silver, platinum, etc.. The prongs are manufactured as a generally square wire which is cut into desired lengths. The wire includes a layer of solder around and along an entire length of the wire. Preferably, the color of solder will approximately match the color of the setting, i.e., the frame and prongs.

It is to be appreciated that the wire may be of other shapes to effect different looks of the setting. For example, the wire may be circular and cut to the desired length. The cut lengths of the wire will vary and will depend on the size and/or the shape of the stone to be set.

In the assembly of the stone and finding as shown in the embodiment of FIGS. 1-3, the stone 10 is placed on the cylindrical frame 12 so as to engage the upper peripheral edge 20, and because of this configuration, the stone 10 is essentially self-centered. Next, the cylindrical frame 12, the stone 10, and the prongs 14 are arranged as shown in FIG. 2 and placed in a suitable jig for holding the assembly. As shown in FIG. 2, a lower portion 13 of the prong will be placed in contact with the sidewall 16 and the bent portion 15 of the prong will be placed in contact with an upper portion of the stone above the peripheral portion 11 of the stone 10. The finding assembly will then be subjected to a sufficient predetermined temperature, e.g., on the order of 1,400° F., so as to solder the prongs 14 to the frame 12, e.g., to allow the solder to reflow and form a joint between the prongs and the frame, and to provide a sturdy grip by the bent portions 15 of the prongs 14 against the upper portion of the stone, thereby resulting in the assembled stone and finding as shown in FIG. 3. By this arrangement, the objective of obtaining maximum exposure of the stone is achieved, at a cost less than the cost of existing findings.

It is to be appreciated that in assembling the setting of FIGS. 1-3, the gemstone 10 employed must be able to withstand high temperatures without becoming damaged. The lowest tolerable temperature of the gemstone must be at least a predetermined amount of degrees higher than the melting point, or reflow temperature, of the solder being employed. Furthermore, the melting point of the solder must be lower than a melting point of the metal of frame 12.

In a further embodiment, a retainer member is employed to center the gemstone received in the frame. Referring to FIGS. 4-6, a retainer member is generally designated by reference numeral 22. In this embodiment, the retainer member 22 is annular shaped and has an outer circumference 24 corresponding to the upper peripheral edge 20 of the frame 12. The retainer member 22 is formed with a layer of solder for bonding the retainer member 22 to the frame. The setting shown in FIGS. 4-6 will be assembled as described above with the further step of disposing the retainer member 22 on the frame 12 before disposing the stone on the frame. By employing the retainer member 22, a gemstone having a girdle circumference 11 less than the circumference of the frame may be used in the setting 1 of the present disclosure.

It is to be appreciated that other shapes and configurations of the retainer member may be employed depending on the size and/or shape of the stone to be set, i.e., a shape of the retainer member will substantially correspond to the shape of the stone, e.g., square, oval, etc.. In the embodiments shown in FIGS. 4-6, the retainer member is configured with an inwardly down-sloping angle best suited for faceted stones. Another exemplary retainer member will include a flat annular ring 130 which will be disposed on the upper peripheral edge 20 of the frame 12 as shown in FIG. 26. In this embodiment, the stone 132 will rest on the retainer member 130 whereby virtually no part of the stone 132 will be disposed in the frame 12 to effect full exposure of the stone. Such a retainer member might be employed with a cabochon stone. The prongs 134 will securely hold the stone in place as described in the various embodiments.

In another embodiment of the present disclosure, the setting 30 is designed to be used with a stone that is not capable of being subjected to elevated temperatures for soldering the prongs 34 to the frame 32. In the embodiment of FIG. 7, the finding 30 includes a retainer member 36 which is soldered to the upper peripheral edge 38 of the frame 32, at the same time that the prongs 34 are soldered to the frame 32. The resulting finding 30 is illustrated in FIGS. 8, 9 and 10. In this embodiment, the prongs 34 are straight and are not formed with bent portions as in the embodiment of FIG. 1.

The straight leg prongs 34 are soldered to the frame 32 without the bent portions so a gemstone may be set in the frame after the soldering has taken place. Since the prongs 34 have solder on all sides, the prongs may be placed in the jig with any side of the prong coming into contact with the frame 32, allowing quick and easy placement of the components into the jig without having to determine which side of the prong has solder disposed on it. After the retainer ring 36 and the prongs 34 are soldered to the frame 32 as described above and illustrated in FIGS. 8-10, a stone is placed on the retainer ring 36, and is self-centered, after which the prongs 34 are bent inwardly to firmly grip the stone. The prongs may be bent to grip the stone by a modified drill press such as the DP-30 Drill Press commercially available from The Foredom Electric Company of Bethel, Conn. The resulting setting with gemstone in place is similar to that shown in FIG. 6.

Referring to FIGS. 11 and 12, another embodiment of the jewelry setting of present disclosure is illustrated. Here, the setting 40 includes a cylindrical frame 42 including a sidewall 44 and a bottom or base 46 with an aperture, a retainer member 48 and two prongs 50. Each prong 50 includes a generally rectangular portion 52 for mating with the sidewall 44 and two prong members 54 for securely gripping a gemstone received in the frame 42. The rectangular portion 52 will be curved to substantially correspond to the curvature of sidewall 44 so when mated the rectangular portion 52 is in full contact with sidewall 44 which in turn will form a stronger joint during the soldering step. In FIG. 11, the prong members 54 include a bent portion 56 and will be utilized with gemstones that can withstand the high temperatures of the soldering process. It is to be appreciated the prongs 50 can be manufactured with straight prong members 54 wherein the prongs 50 will be soldered to the frame 42 without the gemstone in place and, after the gemstone is received in the setting, the prong members 54 will be bent inward to secure the gemstone. In either case, the resulting setting with gemstone in place is illustrated in FIG. 12.

Turning to FIG. 13, a further embodiment of the subject setting 60 is designed to accommodate square stones, and includes a square-shaped frame 62 and a plurality of prongs 64. Each of the plurality of prongs 64 includes a bent portion 66. In assembling the setting 60, a square stone is placed on the upper peripheral rim 68 of the frame 62 so as to be self-centered, after which the frame 62 and the prongs 64 are placed in a suitable jig. The assembly is subjected to a high temperature for soldering the prongs 64 to the frame 62. The assembly of the prongs 64 to the frame 62 is illustrated in FIGS. 14-16.

In a further related embodiment, the prongs 70 are straight as illustrated in FIGS. 17-19. In this embodiment, a retainer member 72 is employed. Although shown as having an inwardly down-sloping angle, the retainer member 72 may be flat for a stone with a flat bottom so no portion of the gemstone is inside the frame and is therefore fully exposed. In assembling the setting 60, the frame 62, prongs 70 and retainer member 72 are placed in a suitable jig, after which the assembly is subjected to a high temperature for soldering the prongs 70 and retainer member 72 to the frame 62. Thereafter, a square stone is placed on the upper peripheral rim 68 of the frame 62 where the retainer member 72 sits so as to be self-centered and the prongs 70 are bent inwardly to grip the stone by a suitable drill press as described above.

Turning to FIG. 20, a further embodiment of the subject setting 80 is designed to be employed as an earring. The setting 80 includes a generally cylindrically shaped frame 82, a plurality of prongs 88 and a retainer member 90. The frame 82 includes a sidewall 84 and a spherical shaped bottom 86. Each of the plurality of prongs 88 includes a bent portion 92. The setting further includes a post 94 which will be soldered to an underside of the bottom 86 of the frame 82. In assembling the setting 80, the frame 82 and retainer member 90 are placed in a suitable jig, after which a stone 96 is placed on the upper peripheral rim of the retainer member 90 so as to be self-centered. The prongs 88 are then placed in the jig, after which the assembly is subjected to a high temperature for soldering the prongs 88 and retainer member 90 to the frame 82. Next, the post 94 is soldered to the frame 82. The assembly of the prongs 88 to the frame 82 with stone in place is illustrated in FIG. 21.

FIGS. 22 and 23 illustrate another embodiment of the setting or finding of the present disclosure, which embodiment is designated by the numeral 100.

Setting 100 is also designed to accommodate stones which are not capable of being subjected to elevated soldering temperatures, with the setting 100 including a frame 102, retaining member or ring 104 and straight leg prongs 106, as well as a post 108. As described above, the retainer member 104 and prongs 106 will be provided with a layer of solder colored to match the color of the frame 102. The frame 102, retainer member 104, prongs 106 and post 108 will be assembled in a suitable jig and subjected to an elevated temperature to allow the solder to reflow and join the components together. The assembled setting 100 is illustrated in FIG. 23.

After the setting 100 is assembled, a stone is placed on the frame 102, and then the prongs 106 are bent radially inwardly to grip the stone as described above.

Turning to FIG. 24, a further embodiment of the subject setting 110 is illustrated. The setting 110 includes a generally cylindrically shaped frame 112, a plurality of prongs 114 and a retainer member 116. The frame 112 includes at least one sidewall 118 and a spherical shaped bottom 120. The sidewall 118 includes at least two cutouts 122 for exposing a bottom portion of the gemstone. In the illustrated non-limited embodiment, the frame 112 has three cutouts resulting in three sidewalls 118. It is to be appreciated the number of cutouts and sidewalls may vary based on the size and shape of the gemstone.

The setting further includes a post 126 which will be soldered to an underside of the bottom 120 of the frame 112.

In assembling the setting 110, the frame 112, prongs 114, retainer member 116 and post 126 are placed in a suitable jig, after which the assembly is subjected to a high temperature for soldering the prongs 114, retainer member 116 and post 126 to the frame 112. After a gemstone is disposed on the retainer member 116, the prongs 114 will be bent by a suitable drill press at a portion of the prong above the girdle of the gemstone to secure the gemstone in place. The assembly of the prongs 114 to the frame 112 is illustrated in FIG. 25. In other embodiments, the assembly could be made without the post 126 which could be soldered to the frame at a later time by applying solder paste to one end of the post.

It is to be appreciated that the setting 110 may employ prongs with an upper bent portion as described in the various embodiments above. In assembling the setting 110 with bent prongs, the frame 112, retainer member 116 and post 126 are placed in a suitable jig, after which a stone 128 is placed on the upper peripheral rim of the retainer member 116 so as to be self-centered. The prongs with upper bent portions (not shown) are then placed in the jig, after which the assembly is subjected to a high temperature for soldering the prongs, retainer member 116 and post 126 to the frame 112. The assembly of the prongs to the frame 112 with stone in place is illustrated in FIG. 25. As can be seen, whether straight prongs or bent prongs are used, the resulting setting after gemstone placement is the same.

In all of the embodiments of the subject disclosure, the resulting finding ensures maximum exposure of the stone including maximum exposure of the peripheral side edges of the stone, as well as providing an inexpensive, but sturdy finding for griping of the stone.
